Figure 4. Biological activity of RhCMVIL-10 mutants M1 and M2 on TF1/IL-10R1 cells.

Figure 4

(A) Cell supernatants containing RhCMVIL-10 single point mutants (described in the Figure legend) (Lys-34Glu, Gln-38Arg, and Asp-144His) were evaluated for their ability to stimulate proliferation of TF-1/IL-10R1 cells in relation to cIL-10 and WT RhCMVIL-10. (B) TF-1/IL-10R1 cell proliferation assay for RhCMVIL-10 M1 (Q38R, D144H) and M2 (E142Q, D144H) cell supernatants. Error bars represent estimated standard error from duplicate measurements.
